An e is moving along the +x direction with velocity . It enters a region of the uniform
of 300 V/cm pointing along +y direction. The magnitude and direction of the magnetic field set up in the region such that e- keeps moving along the x- direction will be:
Option: 1 along -z direction
Option: 2 along -z direction
Option: 3 along +z direction
Option: 4 along +z direction
5 g of Na2SO4 was dissolved in x g of H2O. The change in freezing point was found to be 3.820C. If Na2SO4 is 81.5% ionised, the value of x (K
